Product details
Overview
AUIRFR4292TRL from Infineon is an automotive-grade N-channel D-Pak power MOSFET with 250 V VDS, 275 mΩ typical RDS(on) at VGS = 10 V, and 9.3 A continuous drain current at TC = 25°C. It features 175°C junction temperature rating, fast switching (td(on) = 11 ns, tf = 8.4 ns), and rated repetitive avalanche capability-designed for high-reliability engine control, transmission solenoid drivers, and DC-DC converters in under-hood environments.
For engineers reviewing the AUIRFR4292TRL datasheet, AUIRFR4292TRL pinout, AUIRFR4292TRL application, or AUIRFR4292TRL equivalent, key selection criteria include its 250 V breakdown voltage, low on-resistance at elevated temperature, automotive qualification per AEC-Q101, thermal resistance (RθJC = 1.5°C/W), and D-Pak package compatibility with high-power PCB layouts.
Technical Context
This device uses Infineon's HEXFET® process to achieve low RDS(on) density and robust avalanche performance. Its gate threshold voltage (3.0–5.0 V) enables reliable 3.3 V/5 V logic-level drive, while the 13 nC total gate charge supports efficient high-frequency switching up to several hundred kHz in hard-switched topologies.
The integrated body diode exhibits 1.3 V forward voltage at 5.6 A and 110–165 ns reverse recovery time, making it suitable for freewheeling and synchronous rectification where controlled diode conduction is required. Thermal design is enabled by validated RθJC = 1.5°C/W and RθJA = 50°C/W (PCB-mounted).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 250 V - Withstands transient overvoltage spikes common in 24 V automotive systems without breakdown. |
| RDS(on) typ. | 275 mΩ @ VGS = 10 V, ID = 5.6 A - Enables <1.5 W conduction loss at 9.3 A, reducing heatsink requirements. |
| ID cont. | 9.3 A @ TC = 25°C - Supports sustained load currents in engine management and battery disconnect circuits. |
| EAS | 130 mJ - Allows safe unclamped inductive switching in solenoid drivers without external snubbers. |
| tf | 8.4 ns - Minimizes switching losses during turn-off in high-frequency DC-DC stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4LF8AG | 40 V VDS, 0.95 mΩ RDS(on), LFPAK56 package - lower voltage, much lower RDS(on), not automotive-qualified. | Only suitable for 12 V systems; lacks 250 V rating and AEC-Q101 certification. | Select only for non-automotive 12 V high-current apps where voltage stress is <45 V. |
| IRF4905PBF | P-channel, -55 V, 20 mΩ, TO-220 - opposite polarity, lower voltage, higher RDS(on), no automotive qualification. | Requires high-side gate drive complexity; unsuitable for 24/48 V automotive loads. | Not a functional substitute; only consider if P-channel topology and lower voltage are acceptable. |
Compared with STL220N4LF8AG and IRF4905PBF, AUIRFR4292TRL uniquely delivers 250 V blocking, AEC-Q101 compliance, and D-Pak thermal performance-making it the only viable choice for 24/48 V automotive power switching where voltage transients and under-hood temperature exceed 125°C.

FAQ
Is AUIRFR4292TRL pin-compatible with AUIRFU4292?
No. AUIRFR4292TRL uses the D-Pak (TO-252AA) package with Drain–Source–Gate pin order (D-S-G), while AUIRFU4292 uses the I-Pak (TO-251AA) package with Drain–Gate–Source order (D-G-S). Footprint and solder mask must be redesigned; they are not drop-in replacements.
What is the maximum recommended gate resistor for switching at 200 kHz?
For 200 kHz hard switching with minimal overshoot, a 10 Ω gate resistor is recommended. This balances 13 nC Qg drive speed against ringing from 7.5 nH LS and 4.5 nH LD, as confirmed by Infineon's application note AN-1001 for D-Pak MOSFETs.
Does AUIRFR4292TRL support logic-level gate drive from a 3.3 V microcontroller?
No. Its VGS(th) is 3.0–5.0 V, and RDS(on) is specified only at VGS = 10 V. At 3.3 V, the device remains weakly enhanced (<100 mA ID) and cannot sustain 9.3 A. A level-shifted 10 V gate drive is mandatory.
Can AUIRFR4292TRL replace IRF4905 in an existing design?
No. IRF4905 is a P-channel –55 V MOSFET with opposite polarity, different pinout, and no automotive qualification. Substitution would require full schematic and layout revision, including gate drive polarity inversion and voltage rating reassessment.
